2 Claims.

This invention has for its object a motor plow or sweeper, particularlydesigned for removing snow from sidewalks and the like and also thicklayers of dust, as sawdust, from mill floors, grain and differentgranary floors, etc.

It further has for its object a plow or sweeper in which a snow or dustremoving member is used in place of the knife of a motor lawn mower.

It further has for its object a snow or dust removing member having aspiral vane 5 mounted in a. cylindrical casing for picking up' the snowor dust and moving it axially through the casing from one end to theother, and also having means at its other end for throwing the snow, ordust in a lateral and upward direction out of the path of the plow.

It further hasfor its object a snow or dust removing member andcylindrical casing so arranged that the snow or dust is scooped orpicked up from a fiat surface, and moved through the casing from one endtoward the other end, and then thrown in a direction which is theresultant of forces acting in directions radially and axially of thecasing.

The invention consists in the novel features and in the combinations andconstructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanyingdrawings in which like characters designate corresponding parts in allthe views.

I have here shown my invention as applied to a conventional motor lawnmower with the snow or dust removing mechanism or conveyor mounted onthe lawn mower in place of and driven by the same means as the grasscutting mechanism or knife mechanism. The dust or snow plow includesgenerally a suitable carriage with motor means thereon, snow or dustremoving mechanism including a cylindrical casing extending across thefront of the carriage and open at its front side, the casing also havingan outlet opening in its peripheral wall at one end thereof, a spiralconveyor mounted in the casing for picking up and propelling the snowfrom'one end of the casing toward the other, and integral means forthrowing the snow so propelled or moved axially from one end of thecasing to the other, I in a direction which is the resultantof twocomponent forces, one being the axial force of the 5 conveyor and theother the outward impeller radial force through the discharge opening. I

I designates generally the carriage having suitable supporting wheels 2-and having mounted thereon an internal combustion engine of which 10only the cooling radiator 3 is shown in the drawings, the engine of thisparticular machine being mounted behind the radiator 3. The carriage maybe guided or controlled in its movement by means of handles 4.-

5 designates a cylindrical casing extending across the front of thecarriage and suitably supported thereby, the casing being here shown ashaving heads 6, I at its opposite ends formed with brackets 8, 9 securedto the frame. members It] of the carriage I. The heads are formed withsuitable shoes II for running on the surface or sidewalk or othersurface and thecylindrical casing 5 is open-at its front side, in orderto permitthe snow or dust to enter it while the carriage is travelingforwardly. The casing is provided with a knife, shovel or scoop I2 atits lower-. most side, the advance edge of which extends close to thesurface, ground or sidewalk substan-' tially tangent thereto.

I3 designates generally a spiral conveyor opening I6 at its upper sideat one end .and the vane I5 terminates at that end or at a pointopposite theopeni'ng'lt in ablade II extending in a generaldirectionlengthwise of theaxis' of the member I3. The shaft It is alsoformed witha cone or conical surface I8 at the. end thereof adjacent the dischargeopening I8, and the blade,

I'I meets or joins saidisurface I8; The shaft I4 extends through one ofthe heads, as I, and is provided with means, as a sprocket wheel l9, atits outer end, which is connected, as through a sprocket chain 20, tothe motor driving means on the --carrlage I. fA suitable deflector flfor 50 facilitating the discharge of snow ,or dust to one side oraboveand beyond one end of'the cylin-. drical casing, is provided along theinner side of the opening. The snow removing member I3 is rotated at 55relatively high speed and rims close to the surface of the ground orsidewalk, and when the machine is moved forwardly over the walk into thesnow, the snow is picked up by the conveyor and the knife or scoop i2,and quickly moved axially by its high capacity spiral conveyor mostlydue to its high speed through the casing 5 and to the discharge openingl6, where it is thrown radially upward and outward by the blade II, thisalso being due to high speed, beyond the end of the casing and to oneside of the casing or the machine. The throwing out operation isfacilitated by the conical surface l8.

What I claim is:

1. In a snow or dust plow or' sweeper, the combination with a suitablecarriage and motor means thereon, of a cylindrical casing extendingacross the front of the carriage and being open at its front side, thecylindrical wall having a knife on the lower side thereof terminating atan edge substantially tangent to the ground, the casing having an outletin the upper side thereof at one end, a shaft mounted in the casing andhaving a cone at the discharge end of the casing,

and a spiral vane, the edge of which runs substantially close to theknife and the inner wall of the casing, the spiral vane terminating in ablade extending in a general direction lengthwise of the shaft andmeeting said conical surface, and motion transmitting means between themotor means and the shaft for rotating the latter.

2. In a snow plow or sweeper, the combination with a suitable carriageand motor means thereon, of a cylindrical casing extending across thefront of the carriage and being open at its front side, the casinghaving an outlet in the upper side at one end, a shaft mounted in thecasing and having a headrotatable therewith in the discharge end of thecasing close to the end wall of the casing, and a spiral vane, the edgeof which runs substantially close to the surface over the carriage isbeing moved, the spiral vane terminating in a blade extending in ageneral direction lengthwise of the shaft and meeting said 20
